Mozilla’s Firefox OS isn’t being featured in any premium hardware yet.

Instead, Mozilla seems to be targeting entry-level smartphone buyers, with the openness of the operating system and HTML5 apps likely to give Android some competition.

Android’s success in non-premium sales has proven the liveliness of the low-end smartphone market. And with Apple’s rumoured low-cost iPhone possibly in the works, Mozilla seems be using this opportunity to debut their new operating system amidst less competition.

Both the Alcatel One Touch Fire and the ZTE Open will debut in Latin America, Central Europe, Eastern Europe, and eventually Asia.

The ZTE Open will cost $90 / €69 if you are prepay customer, and will be available tomorrow.
